Minor Issues

Fixed Issues

• Radeon HD 7850 - Water colour varies depending on the camera direction (#116)
  • Obviously caused by a bug in the video driver's shader compiler.
  • Refactoring the shader code solved the issue somehow.
• [Mac] Radeon M295X - Particles below the water surface can be seen through (#541), fixed in [put version here]
  • Caused by reading a depth buffer that is bound to the current framebuffer (depth write is disabled though).
  • Solved by using another framebuffer with the same color attachment but without the depth buffer.
• Intel HD Graphics (1st Gen?) - Application crash (#398), fixed in [put version here]
  • Some old video drivers don't support glGetStringi but OpenSpades still tried to use it, leading to crash.
• [Windows, Mac] Intel HD Graphics 4000 - Graphics Issue with Post Filter "Low" (#114), fixed in [put version here]
  • The alpha channel was messed up

Non-video driver issue

• [Linux] HD Graphics 4600 (Haswell) - Artifacts below text (#605)
